In 1805, Admiral Francis Beaufort devised a guide to assess the speed and force of wind. It is called the ___________.

  1. Richter Scale

  2. Kelvin Scale

  3. Beaufort Wind Scale

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A numerical scale for relating wind speed and sea state, devised by the British Admiral Sir Francis Beaufort in 1805. Beaufort numbers (or forces) range from force 0 (calm) to force 12 (hurricane). Sometimes (and originally) called the Beaufort scale of wind forces.

A Correct answer
Explanation

El-Nino is a warm ocean current that sometimes appears off the coast of Peru in South America during the month of December. It increases the surface temperature of the sea and affects the movement of monsoon winds in the Indian Ocean and causes a drought-like situation in the Indian sub-continent.

"Ferrel law" is also known as  _______.

  1. Jet streams

  2. Wind force

  3. Coriolis force

  4. Cyclonic force
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Coriolis Force: An apparent force caused by the earth’s rotation. The Coriolis force is responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the southern hemisphere. This is also known as ‘Ferrel’s Law’.
